Meanwhile, in Georgia, St. Simons businessman David Perdue and U.S. Rep. Jack Kingston of Savannah won spots in a July 22 runoff for the Republican nomination for the Peach State’s open U.S. Senate seat.

Senate Minority Leader Mitch McConnell

McConnell took 60 percent of the May 20 vote, compared to 36 percent for Louisville businessman Matt Bevin, who had the backing of outside Republican groups critical of McConnell’s leadership, including the Senate Conservatives Fund and FreedomWorks.

However, the commonwealth’s other senator, Rand Paul, bucked his Tea Party supporters to back McConnell.

In Georgia, Perdue and Kingston sat atop a seven-candidate field, with Perdue at 31 percent and Kingston at 26. Former Secretary of State Karen Handel of Roswel came in third at 22 percent.

Two other sitting U.S. House members, Phil Gingrey and Paul Broun, trailed the three front-runners. Some establishment figures in the GOP had expressed concern that a victory by either Gingery or Broun would turn the Georgia seat into a Democratic target in November.
